In a population of beetles, there are green and brown colorations that occur with equal frequency. after a forest fire, only 20 beetles remain. 18 of them are green and 2 of them are brown. what describes this change in frequencies?
a) founder effect provided a new distribution of phenotype frequencies
b) gene flow occurred, as the 20 beetles migrated from a distant location.
c) a population bottleneck occurred, altering the resulting allele frequencies.
d) natural selection selected for phenotypes that blended with green leaves, which did not burn.
